aha… What you are looking for is the holy grail of investing.
I assume your question is academic, so I will try to outline a theoretical possibility.
Be ready to take help of google baba, whenever needed.
Does the holy grail of investing exist? I do not know.
I am very sure that picking winner stocks and keeping them till infinity is not the path towards it.
esp as @VijayNair menitoned its Survivorship bias impacting stock selection.
Think over it.
The 33-year average tenure of companies on the S&P 500 in 1964 narrowed to 24 years by 2016 and is forecast to shrink to just 12 years by 2027
For Nifty 50/500 I couldn’t get the data but I am sure the trend will be similar.
What guarantee I can have that stock which I have picked will perform well in the foreseeable future. Even if i decide to exit, what criteria i can set to exit and what if just after I exit that stock once again pick up the momentum
So just picking up sure shot stocks maynot be investment forever startegy
Or is it?
There are mathematical models available, which try to solve the above problem.
Coffee Can investing theory represents one such model.
In a nutshell, one can pick up the top 10 or 20 stocks which fit in criteria and sleep over them for 10 years. A few will be dudes but the rest of them should give very good returns.
However I have not seen many who have patiatice to sleep over for 10 years, even if stock is underperforming year after year is a test of will power.
The way I look at investing for perpetuity
- Preserving wealth is more important instead of taking risks. Loss may not be recovered, whereas (in comparison ) low risk will help in future to bounce back. Effectively reduction in drawdown is important than maximising profit to avoid sequence of return risk .
- Need to survive across market cycles , Effectively need to consider asset classes beyond stock
Why it is so?
- What we have in the history of stocks is just 100 years of the US stock market. Which is not sufficient for drawing conclusions for forever investment.
Also there are very good( and very ugly) reasons why the USA stock market has performed better than any other country. India Stock market history is even less.
- What if the Indian market crashes like Japan (although it will not) and never reaches its peak? For that matter the US market also has seen gruelling long bear phases. How do we know India may not see it.
Possibly it means for investment forever.
- For equity investment, instead of stock better rely on index
- Global exposure is essential
- Need to look asset class beyond Equity
Academia has suggested one philosophy for investment forever.
Modern Portfolio theory discusses Portfolio management
Quick introduction to Portfolio management is MIT 18.S096 Topics in Mathematics with Applications in Finance, Fall 2013
Cutting long story short, if we mix uncorrelated (or less correlated) asset classes, and do periodic rebalance. We can have an investment portfolio which works across market conditions . It will not give best results in any market condition at the same time it will “work” everytime.
Do we have examples of it?
oh yes!
- Harry Browne’s Permanent Portfolio
- Ray Dalio’s All Weather Portfolio
- Craig Israelse’s 7twelveportfolio
Is it the only way to achieve nirvana?
Well… there are multiple ways to skin a cat.
For a lazy person like me, investment forever means a multi asset, global portfolio with periodic rebalance.
It does not mean this is the only way.
Will it work? (stamp paper per likhaw du kya?
)
it is “supposed” to work across economic cycles, it can’t give better returns.
Also if tomorrow a comet hits earth or more rationally a dictatorial government puts restrictions, it’s not going to work.
Anyhow… anything else also may not work.
Do I believe in it?
Multi asset, periodic rebalance strategy requires (almost) zero prediction about future performance. Yes, as I stated earlier, I am a lazy person, and it suits me best. I follow my own variant of it.
oh god! I havnt answered your question! Simply because I do think its wishful thinking (for me).
How may active mutual fund managers performance is better than index? If majority of MF managers cant do it, I cant do it. Think over it,
