Arindam,
It’s no secret that our dear forum hosts hate Technical Analysis (TA).
I’m not exactly a fan of it, either.
So here’s how I look at the vetting problem. If you’re trying to do a very short-term trade, say, in and out in under 7 minutes, you can get away with not doing any fundamentalist work. But that’s a really risky way to trade, because what you’ll find is this. The best short-term trades are done on stocks that have solid fundamentals. Those are the ones that chart the best and for which it’s pretty easy to find a buyer when you want to get back out. The same is true when selling short. If good old-fashioned, green-eye-shade work suggests that a stock is a piece of over-priced trash, that’s a fact “the market” will agree with soon enough for you cover and get out with the profit you thought you saw.
That’s called gambling – not investing. By the time that you get the news that inspires a “short term” trade, the institutional investors who dominate the market have already reacted and the stock has already moved so it’s too late.
BTW, I fully respect your right to gamble if you wish to do so, but I’m not a gambler. I don’t buy any stock with an intend to sell it. Like Warren Buffet, my favorite holding period is forever.
That said, there are four situations in which I will sell shares.
- I make small trades as necessary to rebalance my portfolio to my target allocation, but these trades are typically less than ten percent (10%) of a position – and yes, I LOVE volatility 'cause I profit from it! These are my only routine sales.
- I have occasionally sold shares in one account and purchased the same stock in another to move a position.
- Whenever I see clear indications that a company in which I own stock has “jumped the shark” (which does not happen often), I liquidate my whole position immediately. I’m getting out of the position before the downturn in business shows up on a quarterly report and everybody else tries to sell, causing the price to crash. JTOL, this is a situation in which I probably should purchase “put” options, but I have not yet done so…
- If I find a company in which I want to invest, I may sell a small piece of my other positions to raise cash for the investment.
But apart from those scenarios, I’m not selling.
You don’t have to take ridiculous risks to do well as an investor. If you invest in Vanguard’s Total Stock market Index Fund, you’ll realize a compound average growth rate slightly ovre 10.6% per year over the long term, which averages out the market’s fluctuations – and you’ll enjoy a very secure retirement with no work whatsoever. But by investing for the long term in well-run companies, you can produce more than double that growth rate and get to a very secure retirement a lot more quickly.
Bonds are a whole 'nother gig. For all practical purposes, they cannot be “traded” at the retail level. They really are ‘buy-and-hold’ investments. Reasons? Historical data used to be nearly impossible to obtain. Spreads and commish are still abusive today, never mind that few brokers give bond investors direct access to the network of underlying desks actually holding inventory. The position you own might not be of a marketable size. Etc. Etc. The obstacles are formidable and endless, compared with stock investing/trading, or forex for that matter. OTOH, bonds are puts, and just like their more familiar counterparts, they can suffer from time decay. So, yeah, then it can make sense to trade out of them to capture a fatter profit than holding to maturity would have offered.
Well, bonds basically are loan instruments – you lend money to a company or a government entity that agrees to pay you back, with interest, when the bond matures. Thus, the intrinsic value of a bond is the present value of the future payments, potentially discounted for any risk that the issuer will default. So, values of bonds go down when interest rates go up because the present value of the future payout diminishes.
Now, bonds can be useful instruments in certain situations. However, it’s pretty apparent that interest rates are going up very quickly and will continue to do so for some period of time due to inflation, causing all outstanding bonds to plummet in value. Thus, this is not exactly a good time to invest in bonds of any kind.
Yeah, “the market” is crashing and for reasons all of us know why. There is nothing “Black Swan” about what is happening. The declines do mean that “the market” has gotten interesting again, and I’ve been shopping hard the last couple of days, adding a couple dozen new positions. So, No. I’m not going to go to cash, nor am I inclined to do so. But neither am I betting big, because we’ve got a lot further down to go.
The $64 question is how much more the market will drop in the present environment. I don’t see inflation abating until there’s an adequate supply of petroleum and natural gas. The Biden administration could help the situation by supporting expansion of domestic production, but just announced another cancellation of sales of drilling rights.
