Note that there's a big jump in implied volatility from 18/Jan/2019 to 15/Feb/2019 calls: the January chain was the earliest LEAP options chain and was used popularly by shorts to bet on Tesla bankwuptcy.
The result is that for example 15/Feb/2019 calls for $400 are currently almost twice as expensive at ~$18 as 18/Jan/2019 calls - which are ~$9.9, there's a lot of short interest included in expectations which are probably not justified anymore. That pricing is probably not justified from a pure time decay POV either (IMHO): it's 91 days vs. 63 days expiry.
So a possible improvement would be to go 18/Jan/2019 calls and then roll them over into February (or later) calls after the January delivery report, to capture the Q4 financial results and 10-Q and the other possible good news.
You could possibly have about 50% higher leverage that way (1.5 times the number of contracts at the same strike price), for roughly the same investment, assuming roughly $350 price levels up to early January. For example right now the 1 month out Dec 14 options at $400 cost around $3. So assuming a trajectory of the stock price of ~$350 up to early January and then a rise, you'd have an effective 90 days cost of $13 instead of $18 - a 40% improvement in leverage.
Of course different stock price trajectories with different outcomes are possible as well: for example a January expiry + roll-over wouldn't capture a string of bad news up to 18/Jan/2019 followed by expectations of a string of good news up to 15/Feb/2018, which would make the roll-over more expensive.
It also depends on how close to the current stock price you intend to have your 15/Feb/2019 call options. Below $400?
Anyway, not advice.
