Common Equity Investing Mistakes

The errors that damage a first share portfolio are consistent across households. They are not exotic. They are tips followed without reading, too much money in too few names, borrowed exposure, and the conversion of every decline into a forced decision. Knowing the list will not make you immune. It will make the mistakes recognisable while they are still small.

Mistakes That Recur

1. Buying on a recommendation you cannot explain. If you cannot describe what the company sells and how it earns, you do not own a business. You own a ticker.
2. Concentration. Putting 30–40 per cent of equity into one name turns a single result into a household event. Funds exist to prevent that. Direct holdings should not recreate it.
3. Adding to a losing position only because the price is lower. Buying more is justified only if the original thesis is intact and the capital at risk remains acceptable. A lower price can mean the thesis was wrong.
4. Using leverage or derivatives to “make up” a loss. This changes investing into a recovery attempt. The recovery attempt is how losses become larger.
5. Watching the price every hour. Businesses do not change hourly. The habit trains the investor to trade.
6. Applying for every widely discussed IPO without a view of the business or the price. Listing day excitement is not a research process.
7. Selling a sound holding to fund a more exciting new name. The portfolio then becomes a queue of recent ideas rather than a set of understood businesses.
8. Ignoring debt on the company’s balance sheet. Equity is the residual claim. Heavy borrowing can erase that residual in a bad year.
9. Using money earmarked for a near-term payment. A three-year house booking does not belong in three stocks.
10. Stopping the mutual fund SIP to increase the demat balance. The core is then weaker and the satellite is larger — the opposite of the structure in Article 3.
