Sensible guide to readjust your portfolio in this turmoil
Conceptually, it helps to segregate your investment and trading accounts.
In your investment account, one should not even think about whether a stock is 52 week high, 52 week low, above this moving average or below, what momentum shows or not. Technical analysis is a total distraction in your investment account; in fact, can be actively harmful.
The only thing that should matter is whether this company - the actual business - can plausibly compound earnings on a diluted basis by a high enough number, over say the next five years, and whether one is getting the same at a reasonable valuation with limited downside.
For that one will have to understand the enterprise in depth but also the sector, country and beyond. With primary research, not just secondary research.
While past is not prologue, there are ~85 listed businesses in India today, for example, which have had EPS compounding over the last 5 years (so from pre-Covid) north of 25% CAGR, market cap north of 2500 cr, and dividend yield north of 0.5%. Not that these are cutoffs which are hard and fast - not at all - but just to get a sense.
Such an approach - what we call PIPE investing, or public investing albeit private equity style - cuts out a lot of the BS. As Buffett said, if you are comfortable owning a part of a business that you cannot sell for five years, then that is a good approach to investing.
