I believe both puttable and callable are preferred in bearish markets not only puttables …
This is getting misleading…
So when interest rates are falling, call underperform because of their negative convexity nature and puts perform better but is the latter’s performance better than bullets? I believe bullets outperform in lower interest rates but now im confused.
Both putables and callables outperform bullets in rising interes environment (ie. have samller losses) and bullets outperform both putables and callables in declining interest rate environment (have larger gains)
