I noticed that he conflated the safety of a T-note* with the asset price. US Treasuries are AAA-rated super safe guaranteed returns because they're not expected to default or miss a coupon payment, and they'll be redeemed for the full value when they mature. That doesn't mean they don't have market prices that fluctuate.
*T-bills are up to 52 weeks maturity.
Thanks for the note! I'll change the wording in my article WRT bills/notes. :)
With regards to safety, I noted that I think there are two types of safety to note here:
1. Default risk. 2. Asset price volatility.
Ultimately if someone is willing and able to hold to expiry, they aren't subject to #2, but this clearly wasn't the case with SVB and may also be the case with other institutions. I think it lacks nuance to not consider the middle states between the purchase of a bond and the full return of the bond upon expiry.
It "might work if nothing significant happens" but that is just a weasel way of saying it doesn't work.
Now if you're saying you decided to invest in something and you're trying to get an entrypoint and you spot a moment of large deviation from the mean and you use that to influence your operational buying mechanics like how you space out your buys or time them, that I can definitely see. But online you always see these two very different things mixed together.
I don't employ any technical analysis in trading, nor am I a strong advocate, but technical analysis is more about reactionary psychology than about predicting the future. In the most micro sense, the market is dictated by single individuals buying and selling stock, and in the broadest sense, it's a statistical result of millions, or billions of unknowns. Those are two totally different games.
