The reason that the calls appear to be down is because due to lack of trading, the last price occurred yesterday or earlier at a lower stock price. For example, the Jan '21 145c is $45.30 x $47.40 with a last trade of $39.90 . It's a stale quote.
There are lots of issues with these LEAPS. They have low Open Interest, most haven't traded today, the few that have traded are in single digits, the IV is high and the B/A spreads are Holland Tunnel wide. That's a recipe for disaster unless you work the numbers.
The starting point is to determine the midpoint of the spread. For the above option, it would be $46.35. But just to be sure, put that price in a pricing model to make sure that the IV lines up with that of the other options and the average implied volatility for that expiration.
For a somewhat liquid option, the midpoint might be a reasonable price to get a fill, should a counter party show up. For LEAPs like these that trade by appointment, it's possible but not likely.
With B/A spreads like these, you really need to have courage of conviction to buy these LEAPs at the market price. If the call is ATM with approximately a delta of 50, the underlying will have to move up $2 for every $1 of spread that you pay in order to break even.
