We use similar strategies. When I buy calls I typically buy for the longest time possible and well in the money. I've taken a big hit too these last few months but I suspect my Jan 2016 110s and Jan 2017 160s will recover well before they expire. I bought some of the Jan 2016s with practically no time premium and so there's virtually no time decay. My recent purchase of a couple March 200 strikes is an educated gamble. It may pay off, it may not, but it's such a small part of my portfolio that I can stand to take the loss.
I always keep some money for buying on irrational short term SP down moves.
As far as I can see, the recent down slide started roughly after "Elon, show me the D"-event where TM revealed the high performance AWD version P85D for Model S.
While I can understand thoughts about correlation of oil prices and some industries and maybe even EV sales as well, my opinion is that this correlation is about getting exaggerated now. At the same time Tesla resolved some minor issues (production ramp up of AWD, new seat / airbag issues, SW-version, charging in China).
Most Tesla customers do not buy their Tesla cars (high ASP) to save money (because riding on electricity saves them some cents compared to guzzling gas at the pump).
Most cars are sold for emotions / way of life, not because a new car saves the new owner some money, and Tesla does deliver exactly here.
Tesla owners know that Tesla-grin/-smile you get every time you hit the accelerator and unwillingly start to smile about that unbeliveable smooth and intense acceleration, just give it a try yourself, it's amazing!
This tremendous driving pleasure of a Tesla Model S is what makes people driving cars of all kinds of companies (Merc, BMW, Porsche, Toyota, ...) change their mind and buy an EV, namely a Tesla. These fact are the source for the new car brand Tesla that is growing stronger and stronger every day potential customers see and experience Tesla products aroud the globe.
This is what continuously drives worldwide demand for Tesla vehicles in such a way that people on this planet put their money down for a car (maybe without test drive like Model X) and wait years for delivery, not expensive oli prices.
And this entire story hasn't changed during the past months, by contrast Tesla has shown the global automotive industry and worldwide customers their latest advances of a high performance electric propulsion powertrain, namely 3.2 sec, 700hp, 500km AWD range P85D Model S.
Adding that this powertrain will gain even more performance during the years to come (average 8% annual improvement rate on Li-Ion tech for next 10 years).
Best is, this is no cheap talk about some prototype or future car, but serious state of the art high performance EV technology already on sale at your damn local Tesla store!
Go, figure it out ask your sales rep about some facts!
Long story short, I bought small amounts of shares during last week's trading for the first time in some weeks.
I intensify buying during next days/weeks on flat SP or any dip.
I consider to add shares and long term calls deep ITM during next days/weeks.
Next Thursday is EZB meeting about QE in Europe, I'll watch out for any news.
By the way my opinion is that in the mean time everybody expects a small miss of 500 to 1000 cars in terms of deliveries next ER.
I do not expect this to be a major issue as at the current level this slight miss is already factored in SP and the factory is currently up and running and cranking out cars like never known before. Based on weekly production rate I expect positive news about production numbers at next ER that is already in Feb. This'll translate in record deliveries during next Q1 and Q2 ER.
Please do your own research and happy investing.
