It is useful to think about ways and means of keeping the level of the market from swaying our investment decisions completely. If your favourite restaurant runs a discount on its Mexican menu, you may not choose to have it for breakfast, lunch and dinner, only because it is cheap, isn’t it? You would surely think that whether you are hungry, and whether you like Mexican cuisine are more important than the rock bottom price. Importantly, your choice of what you will eat will be driven by you, rather than what is on offer. We need to bring that common sense principle into investing as well. To an investor who hates any loss in the value of his portfolio, equity markets are a no-no even if the index is at a very attractive level. Just as my father will refuse to have pizzas for dinner, and my son will cringe at porridge. Therefore step one is to ask whether we like to be in the markets at all, and understand why we want to be there. If we figured that what we do with our investments has to stand on its own, driven by our needs and preferences, half the battle is won.

Sadly, just as we sneak in a samosa even as we are working out the fat, we find it so tough to actually implement what is good for us. There are well known behavioural traits that we have, which come in the way. Many of them bias our judgment and our decision. We may like to invest some money into equity at the current levels, having seen that corporate profits are healthy and fundamentals are good. But we will be worried about the fall in price that we have seen. It is so important to see some rise in price, before we buy, because we are led by our recent experiences. We are enthusiastic buyers when markets have moved up, and when everyone else seems to be buying. We seldom buy cheap. Somehow we think it has to be a good thing to do, if many people are doing so. Then, we like what we buy and refuse to accept that we could have a loser on hand. When we see prices falling, we convince ourselves that prices will somehow recover to our price. We are very clued to our price, that it becomes some kind of mental benchmark. But the market does not know this and is unlikely to care. So we tend to keep losers, and refuse to reckon the loss. If we bought at Rs. 100 and the price fell to Rs. 20, we lost 80%. When we continue to hold what we bought, and hope it will go back to Rs. 100, we are expecting a 400% increase – not realistic isn’t it? At every decision to buy or sell, we need to fight the bias to implement what is good for us, and many of us find it tough to do so.

The moral of the story is, we may have a nice little strategy of investment, but if it is driven only by the level of the market, and not by our needs, there is a risk. That risk becomes higher, when our decisions about the markets are biased and our thinking about the market and the way we make our decisions are far from optimal. When we combine the craving for the right time to buy into the market, with the biases that we suffer, we could put our investments in danger.

There are two things we could do, if we accept that this is a problem, and that we need to do something about it. One – we have a plan that we implement, without caring about where the market went. Two – we let professionals manage our money, so the call on markets is not biased. The mutual fund choice is sensible, because it enables us to implement disciplined investing in our own way, leaving the "market watch" to the fund managers. And having the fund managers to watch your money is a nice way to side step the bias. A fund manager is bound by investment processes and risk controls that take care of bias we will suffer when we deal with our own money.
