The peak you measure from

The portfolio is ₹54,20,000 and the feeling in the room is that something has gone wrong, because in December it was ₹62,00,000. The plan does not mention ₹62,00,000. Nothing mentions it, except the screen, and nobody chose it.

It is a Sunday in June and the number on the screen is ₹54,20,000. The mood is poor, and the reason given, if anybody asks, is that in December it was ₹62,00,000. Nothing has been sold. Nobody has changed jobs. The ₹40,000 has gone in on the fifth of every month throughout. The written plan — which exists, which is unusual, and which nobody has opened since it was written — says ₹3.5 crore by 2039 and says nothing at all about ₹62,00,000. That figure is not a target, not a cost and not a commitment. It is the highest number the account has ever displayed, and over six months it has become the standard against which this household grades itself, without anybody proposing it or agreeing to it.

Think of it like this
The bill from the month the flat was empty

One June the family travelled for three weeks and the electricity bill came to ₹740. For two years afterwards every ₹2,900 bill felt like carelessness, and there were arguments about the air conditioner. The ₹740 was never a standard anybody could live to. It was produced by an empty flat — by conditions nobody would want repeated — and it became the number in everybody’s head purely because it was the lowest one they had ever seen.

In the market

A portfolio peak is produced the same way: by whatever the market was doing on one particular afternoon, in conditions nobody can arrange again. It then becomes the figure every later Sunday is measured against, not because it describes anything, but because it was the largest number that ever appeared.

Three true descriptions of the same ten months

Worked example
What the ₹7,80,000 is, and what it is not
A household portfolio with ₹40,000 going in on the fifth of every month
Value at the start of AugustTen months before the Sunday in question₹49,00,000
Value in December, the highest it has ever beenFour months later. This is the figure that becomes the standard₹62,00,000
Value now, in JuneSix months after the peak₹54,20,000
Description one — measured from the peakThe only one of the three the app displays, and the only one the household has said out loud. The distance from a peak has a name — a [[drawdown]] — and it is a real measurement. It is simply not a measurement of what the market did, nor of the planDown ₹7,80,000, or 12.6 per cent
Contributions during those six monthsPaid in while the value was falling, and therefore working against the fall in the arithmetic above6 × ₹40,000 = ₹2,40,000
Description two — what the market did over those six monthsThe market took ₹10,20,000, not ₹7,80,000. Measuring from the peak credits the household’s own deposits against the market and makes the fall look smaller than it was₹62,00,000 + ₹2,40,000 − ₹54,20,000 = a fall of ₹10,20,000
Contributions across the whole ten monthsIncluding ₹1,60,000 during the rise to December10 × ₹40,000 = ₹4,00,000
Description three — the whole ten monthsSo the market added about ₹1,20,000, which is roughly 2.4 per cent on the August value. Ten unremarkable monthsUp ₹5,20,000, of which ₹4,00,000 was deposited
What each description makes the household want to doThe first says something is broken. The second says the fall was real and larger than reported. The third says carry onPanic, then respect, then nothing
All three descriptions are arithmetically correct and only the first is on any screen. Note what makes the first one unusual: it is wrong in both directions at once. It understates what the market actually did, because it silently counts the household’s ₹2,40,000 of deposits as a recovery. And it overstates the damage to the plan, because the plan was written against ₹3.5 crore in 2039 and never against ₹62,00,000, so a fall from the peak is not a shortfall against anything the household undertook. Each error conceals the other, which is exactly why the comparison survives inspection and gets repeated. One honest caveat: the ₹10,20,000 treats six months of contributions as though the market acted on all of them equally, which it did not — the direction of that correction is what matters here, not its last digit.

The ratchet

A reference point is whatever number a gain or loss is judged against, and this one has five properties that between them explain its grip. None of them is a property anybody would choose deliberately.

  • It only ever moves up. A new high replaces the old one; a fall does not lower it. So the figure you are comparing against is, by construction, the single most flattering value your portfolio has ever had — a high-water mark in the literal sense, in which the mark stays on the wall after the water has gone down.
  • It was set on one day. Whatever the market happened to be doing that afternoon is now the standard, and the conditions that produced it are not conditions anybody can arrange again.
  • It contains your own deposits. For a household saving every month, the peak is being reset by its own contributions: in a completely flat market, a portfolio receiving ₹40,000 a month sets a new high in every single month. Which means a new high is not evidence of anything, and the distance from one is not a return.
  • Most days are not new highs. In a market that moves both ways, a new high requires exceeding every previous day, and a series that rises in fits and falls back spends the great majority of its days somewhere below its own record. That is the counterpart of the previous point rather than a contradiction of it: contributions push the mark up in steps, and the market between those steps is what puts you under it. Being below the peak is the ordinary condition of a portfolio that is growing, and it is being read as a fault.
  • It has no author. Nobody wrote it, nobody agreed it, it appears in no plan and it cannot be revised, which is precisely why it is never argued with. Every other number the household uses had to be justified by somebody.

What the comparison costs

  • The plan gets abandoned at the worst moment. "We are down ₹7,80,000" is the sentence that stops a monthly instalment, and the arithmetic underneath it says that over ten months, with deposits set aside, the market added about 2.4 per cent. The instalments that would be skipped are the ones buying at lower prices.
  • Actions get made conditional on a level nobody owes you. A rebalance, a goal payment, a sale already decided on, all postponed until it "comes back". Another lesson in this track deals with recovery anchoring after a large loss; the version here is milder, more common and applies to ordinary six-month falls in perfectly healthy portfolios. The peak has a date it was set on and no date by which it has to be regained, so a condition written against it has no deadline and may go unmet for years.
  • A new high gets read as skill. The mirror error, and the more expensive one, because it leads to sizing up. If deposits alone are setting new highs every month, the high is a fact about your savings rate and not about your judgement.
  • [[Absolute return]] on the app compounds it. The headline figure treats last month’s instalment identically to a rupee invested five years ago, so the number the peak is measured on is itself flattered by the deposits — and both distortions run in the same direction.
Two things a household can grade itself against
The peak
  • Updates itself, upwards only, with no notice.
  • Is always the best value ever seen.
  • Counts your deposits as though the market produced them.
  • Makes most Sundays a failure.
  • Has no author, so cannot be argued with.
  • Produces the urge to act.
A number you wrote down
  • Is an amount and a date, chosen by you.
  • Moves only when you decide to move it.
  • Counts deposits as deposits and returns as returns.
  • Makes the question "are we on the path" answerable.
  • Can be disagreed with, including by you next year.
  • Produces a review.
Choosing what you compare against, before the next fall
  1. 1
    Write the plan figure where the app is

    The amount, the date and the monthly contribution it assumes, on one line, somewhere you will see it when you open the account. The peak wins by default because it is the only number in the room; most of its power goes the moment there is a second one.

  2. 2
    Split deposits from returns every single time you look

    Two lines: what we put in, what the market did. This is the whole repair, because every distortion in this lesson comes from those two being added together and displayed as one figure. It also makes a genuinely bad six months legible as one, which the peak comparison does not.

  3. 3
    Fix the comparisons you are allowed to use

    The plan path, and a broad total-return index over the same dates with the same cash flows. Another lesson in this track sets out how to compute your own return honestly; the point here is that the list must be short and decided in advance, because in a bad month you will reach for whichever comparison is nearest.

  4. 4
    Write the peak’s date next to the peak

    A high from eighteen months ago, in a market that has since fallen broadly, is a fact about the market rather than about your decisions. Undated, it reads as something you had and lost. Dated, it reads as what it is.

  5. 5
    Review on a date

    A fixed month, in the calendar, the same one every year. A review triggered by a feeling is triggered by exactly the conditions in which the peak comparison is most persuasive, which is the worst possible sampling of your own attention.

◆ Your call

Somebody says: we have lost ₹7.8 lakh

December’s value was ₹62,00,000, June’s is ₹54,20,000, and ₹40,000 has gone in every month throughout. The plan says ₹3.5 crore by 2039. Nothing has been sold and no circumstance has changed.

Check yourself

A portfolio peaked at ₹62,00,000 in December and is ₹54,20,000 in June, with ₹40,000 deposited every month in between. Which statement is correct?

1.A plot bought in 2015 has never appeared in the household’s annual review. What is the mechanism, and what does it cost?

2.Why does a household cancel ₹4,315 a year of subscriptions on the same afternoon that it leaves ₹34,100 a year of fund charges untouched?

3.A household with ₹22,00,000 in equity funds, ₹19,00,000 in a provident fund, ₹8,00,000 in a public provident fund account and a ₹6,00,000 deposit moves its fund account from 100 per cent equity to 70 per cent. What has it actually done?

4.Why is "we are down ₹7,80,000 from our December peak" an unusually durable error?

Simple bhasha mein
Us mahine ka bill, jab ghar khaali tha

June ki Sunday, screen pe ₹54,20,000, aur ghar ka mood kharab — kyunki December mein ₹62,00,000 tha. Kuch becha nahi, naukri wahi, aur har mahine ki 5 tareekh ko ₹40,000 jaata raha. Plan mein likha hai "2039 tak ₹3.5 crore" — ₹62,00,000 kahin nahi likha. Woh na target hai, na lagat; woh bas ab tak ka sabse bada number hai jo screen ne dikhaya, aur chhah mahine mein ghar ka paimana ban gaya. Teen sahi hisaab hain, dikhta sirf ek hai. Ek: peak se ₹7,80,000 neeche, yaani 12.6%. Do: un chhah mahino mein ₹2,40,000 daala bhi tha, toh market ne liya ₹10,20,000, na ki ₹7,80,000 — peak se naapne mein aapka apna paisa market ke khaate mein jama ho jaata hai. Teen: August mein ₹49,00,000 tha, ab ₹54,20,000, yaani ₹5,20,000 zyada — par usme ₹4,00,000 aapne daale, toh market ne diya kareeb ₹1,20,000, matlab 2.4% — dus aam mahine. Pehla hisaab dono taraf se galat hai: girawat ko chhota dikhata hai aur plan ka nuksaan bada — aur isliye pakda nahi jaata, ek galti doosri ko chhupa leti hai. Peak ki aadat samjho: woh sirf upar jaata hai, ek din ke mood se banta hai, aur aapke apne jama kiye paise se banta hai — flat market mein bhi har mahine ₹40,000 daalne se naya peak ban jaata hai. Jaise woh ₹740 ka bill, jo teen hafte ghar khaali rehne se aaya tha aur do saal tak sabko taane sunata raha. Do line har baar likho: kitna daala, aur market ne kya kiya. Plan ka number wahan likho jahan app khulti hai, aur review tareekh pe karo — peak sirf isliye jeet raha hai ki kamre mein doosra number hi nahi hai.

What to remember
  • A peak only ever moves up, was set on one day, and contains your own deposits — so it is the most flattering figure your portfolio has ever produced.
  • Measuring from it is wrong twice: it credits your contributions against the market and treats a fall as a shortfall against a plan that never mentioned it.
  • With money going in monthly, a flat market still sets new highs — so neither a new high nor the distance from one is a return.
  • Split deposits from returns every time you look; every distortion in this lesson comes from the two being displayed as one number.
  • Write the plan figure where the app is, and review on a date — the peak wins by default only because it is the only number in the room.
