While there’s no way objectively quantify the political ramifications of the failed assassination attempt on former President Trump over the weekend, history suggests–at the very least–that such occurrences are not damaging for a candidate’s political capital.  As one example, Reagan’s approval rating immediately jumped 8 points after being shot in 1981.  There does seem to have been an initial market reaction in the overnight session, but much like with the presidential debate reaction, it was very underwhelming in the bigger picture.  This doesn’t preclude a bigger reaction in November, but as in 2016, the most important political change would be one that results in a one-party sweep (House, Senate, Oval Office).
