83% times equity investment gave over 10% returns: Is 7 years the best minimum holding period for higher returns?

economictimes.indiatimes.com:

A report from FundsIndia — Wealth Conversations February 2024 — has an interesting insight: if you had invested in a basket of NIFTY 50 stocks on any day since June 30, 1999, and remained invested for a minimum of 7 years, it would have delivered more than 10% returns 83% of the time, as reflected by the NIFTY 50 TRI.

What is the best minimum period for which one should invest in equities?

Does it mean that when people plan equity investment, they should aim to remain invested at least for 7 years to enhance their chances of double-digit returns and meet medium-term goals?

“While in the short run the markets behave like a voting machine and are driven more by sentiments, in the long run, fundamentals almost always take over the sentiments and the stocks start reflecting their true value,” says Raghvendra Nath, MD, Ladderup Wealth Management. “Over extended periods, the equities average out the volatility and therefore the probability of earning superior returns improve. Seven years is not a magic number though. It is generally recommended that when investors are investing in equities, they should only put that portion of their wealth that has to be preserved and grown over a long period.”
