you are exactly right !
A paltry bounce back both on the bond and common stock portfolio, purely from a realized/unrealized capital gain/loss point of view.
That explains the mediocre 3% bounce back on the book, in turn.
494 million return on bonds portfolio of ~$17 billion + 130 million returns on the common stock portfolio of 3.8 billion
The crown jewels* are, however, grouped under the Associates (~$4.6 billion in value). For, those unless there is an impairment charge, you wont see the their stock movement captured in page 15, I believe. But overtime, one should see FFH's portion of earning to do better if those associate perform better.
I should state however that one-quarter of S&P500 is made of BigTech/FANG, and the aggregate bounce back of the BigTech lifted the S&P500 far better than Blackberry powerhouse bounce back did within the FFH common stock portfolio. If you are competing against S&P500, you need either of the following two things: (1) either you got the genius to do without Big Tech in the portfolio and still do really well or (2) have at least as much Big Tech as the index, and you can get creative on the remaining 3/4 of the portfolio.
*crown jewels net of Resolute, as RFP is no jewel let alone a crown jewel
