Buy, hold vs. market timing Premium

Explore the trade-offs between buy-and-hold and market timing strategies to enhance your investment returns and minimize regret.
You may be a buy-and-hold investor or a market timer. How did you feel about the sharp decline in silver ETF prices after they touched an all-time high? Did you regret not taking profit at higher levels? Or did you take profit only to see prices move up further? Let discuss trade-off between strategy of buy-and-hold and market timing.
Take an investment of ₹50,000. Its value slips by 20% in a year and rises by 20% the following year. The investment value at the end of the first year will be ₹40,000 and at the end of the second year it will be ₹48,000 resulting in a geometric return of -2.02%. However, the arithmetic return of zero (average of -20% and + 20%) suggests investment value was unchanged. Clearly, it is not the case. The geometric return is lower than the arithmetic return because of volatility. Interestingly, this difference in return is referred to as volatility drag. Note, a buy-and-hold strategy will generate lower returns in volatile markets — higher the volatility, greater the drag. This drag is approximately one-half of the variance of the returns.
The other side to buy-and-hold strategy is market timing. Empirical evidence suggests that individuals are typically not good market timers.
Research shows the buy-and-hold returns on investments are significantly higher than the actual returns of a market timer.
This difference is referred to as behaviour gap. It is attributed to error in human judgment — buying when prices rise sharply and selling in panic when prices fall.
How should you balance the volatility drag and the behaviour gap?

The U.S. has launched two investigations under Section 301 of the Trade Act of 1974 against India and other economies to examine practices that may be ‘unreasonable or discriminatory and burden or restrict U.S. commerce’. One probe examines whether countries, including India, are using excess manufacturing capacity to export to the U.S. in a manner that hurts American businesses, while another looks at whether countries have taken ‘sufficient steps’ to prohibit imports of goods produced with forced labour.
