Today on the Finance Flash Go! podcast, I’ll share my thoughts on familiarity bias in stock investing.
Familiarity bias is when we feel that an investment is good, or even worthwhile, because we are familiar with it.
We feel that we have some “insider” knowledge of a product, industry, field, technology, you name it. So, we believe that we can leverage this familiarity and perceived knowledge to invest and outperform the market.
This plays out allllll the time, especially in stock investing. Someone works in product development and thinks some new technology will push some product into the stratosphere. So they buy some stock in the company with the technology and/or product.
As physicians, we are particularly susceptible to this bias
If I had a dollar for every doctor that has told me they like to invest in medical technology because they really feel it is going to take off…Oh yeah, and because they feel they can understand it, I could shave a few years off of my retirement.
That’s exactly the problem with familiarity bias. It lulls us into a false sense of security. All of a sudden, we think we can beat the stock market and time the market and do all these sorts of things that we just can’t.
When you invest, you are minimizing risk and maximizing return.
The only way to do this in the stock market is through index fund investing and approximately the market. In doing this, I pin my hopes and money on the entire US and world economy. If something good happens for me and my money, it’s happening for everyone.
When you speculate, you are hoping and banking on something happening that is good for you and inherently bad for others. Right?
You are making a bet, and someone has to win and someone has to lose.
Even if you are making a small bet, like on medical technology stocks because you are a doctor and know the field, you are still speculating.
Think about your investments right now and see if you are relying, even a little, bit on the speculative component on the stock market’s value.
If so, I would strongly consider adjusting to minimize your risk and maximize your reward.
