Sometimes I believe in as many as six impossible things before breakfast.<\/p>\n

In Texas a shooter goes to the side of a barn\u00a0and fires 20 shots. He then finds 5 hits that are next to each other and draws a bull eye around it and claims to be a sharpshooter. This joke is the basis of what is called the “Texas sharpshooter fallacy”.<\/p>\n

 <\/p>\n

The assertion of sharpshooting cannot be replicated but the evidence is there for all to see. And the evidence blinds us to ask the most important question – future replicability.<\/p>\n

 <\/p>\n

Similar sharpshooting happens in investing all the time. Here are some example you may come across:<\/p>\n

1. Showing and talking about winning trades on social media to get people to sign up for expensive investing courses or option seminars.<\/p>\n

2. Promoting thematic baskets that have done well recently as evidence of skill to charge high fees.<\/p>\n

3. Bragging about multi-bagger stocks in parties for social gratification (w\/o disclosing portfolio allocation\u00a0or stock\u00a0portfolio returns).<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Carl Sagan, the famous astronomer and planetary scientist,\u00a0once\u00a0said “Extraordinary claims require extraordinary evidence<\/em>“. He was only paraphrasing French mathematician Laplace who framed the principle some two centuries prior as “the weight of evidence for an extraordinary claim must be proportioned to its strangeness.<\/em>” – strangeness being how infrequently the claim\u00a0is observed.<\/p>\n

 <\/p>\n

Now think about a thematic basket that shows evidence of ~5% outperformance to Nifty 50 in a\u00a03 years backtest and implicitly through clever wordings promises something similar\u00a0for the next 15 years \ud83d\ude42<\/p>\n

 <\/p>\n

How strange or extraordinary is this claim? Or to put it differently, in all the\u00a0fund manager \/ investor return data we have, how many times do we see such extraordinary returns sustained over 15 year periods?<\/p>\n

 <\/p>\n

In 40 years of market data\u00a0the odds that your thematic basket manager\u00a0would string a 15 year track record of extraordinary performance like above is ~ 1 in 32,000. (Ps: some baskets\u00a0claim 10-15% annual outperformance\u00a0?. The odds there would be a magnitude lower still.)<\/p>\n

 <\/p>\n

That is 0.003%.<\/p>\n

 <\/p>\n

This\u00a0is your odds of finding\u00a0such a thematic basket manager\u00a0as well. The evidence of a 3 year backtest (not real performance and not including costs) is paltry faced with such extraordinary claims. Same holds\u00a0for the option seminar peddler showing 10% monthly returns. Cropped screenshots (probably doctored) of random days showing big returns just does not cut it as evidence of such an extraordinary claim. It is negligible\u00a0evidence built on super shaky grounds and\u00a0no rational person should\u00a0fall for this. But many do, because of two reasons. One, they don’t realise how extraordinary the claim is and two, their brain goes into “greed” mode and rationality takes a backseat.<\/p>\n

 <\/p>\n

As an investor be careful on which investment sharpshooter puts a nice bulls eye around your hard earned wealth.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
