LIDAR has been used for decades by police for speed monitoring. How has this not come up before? In that use case they are shooting it right at your windshield (and presumably face).
Question.
What stage are the shorts in today?
What stage they will be in after ER?
Raises the question of whether I should roll options (on a SP high) to March rather than 15 Feb. And if so, whether I should wait for the announcement or roll over sooner for less theta decay.
Year end fin. statements are usually audited (and signed by auditor) and take more time to produce. Quarter audits may be more lenient with promise to fix all open questions by year-end, and auditor are usually hard-nosed at the year-end financials, and want everything closed to their satisfactions, including more testing of controls etc...The big question is whether one should expect any arbitrary Q4 to be late (e.g. time required for year-end filings), or just interpret that as an artifact of how few datapoints we have. Raises the question of whether I should roll options (on a SP high) to March rather than 15 Feb. And if so, whether I should wait for the announcement or roll over sooner for less theta decay.
My thoughts are I should probably set a cutoff... say, if there's no announcement by the Friday the 25th or Monday the 29th, then I should roll over. Maybe not even to March, maybe just 22 Feb .. heck, maybe I should just go ahead and do that. It'll probably cost me a contract or two to buy the extra theta if I do that, though (plus fees)...
Theta decay is unstoppable and cannot be avoided via rollover. Theta is the price call buyers pay to call writers to assume the time risk of the options.
As @Cherry Wine said it too, this is difficult, generally you can only neutralize theta decay by:
Each of these aporoaches have pros and cons, and I might have missed other approaches.
- Financing Theta decay by assuming new risk, such as selling half of your options when Vega and Gamma seem high enough and wait some time with half a position and cash. If the SP drops after this, or Gamma gets lower due to sideways price action, you might be able to buy back a longer expiry and essentially use your Vega and Gamma gains to finance the Theta decay. Another way to assume more risk is to increase the strike price. Note that even if you get it wrong, you'll still have half of your options and are able to capture further rises in a leveraged fashion.
- Financing Theta decay externally. Just pay the higher price with dry powder.
- Financing Theta decay internally via reducing the number of contracts or by shifting up the strike price. This will gradually erode the options with every rollover if it's a losing position or if profits are smaller than Theta decay, but if you got the direction right it would allow extension of expiry.
Maybe options traders can chime in?
I finally got some info that it is indeed true that the European Model 3 will only be able to supercharge over the CCS port and not over the Type 2 port (unfortunately). On the Belgian Model 3 resevation FB group, somebody showed an answer from a Tesla employee on how to know which supercharger has been converted to dual cable. In the future the Tesla site will be updated to show this, and Model 3 will only show converted superchargers, and the navigation will only route through converted superchargers.They only upgrade some of the stalls. Thats asking for trouble between S/X drivers and 3 drivers. At the rate they are currently upgrading the stalls, it will take a year before the suc network is useful for model 3 drivers, unless model 3 can supercharge over the type 2 connector. I expect next gen s/x to also have ccs2 natively, so soon type2 only s/x will be a minority.
Decay is faster as it gets nearer to expiration - so rolling can slow rate of decay
Sell Puts/Calls and negate total portfolio decay ..
This is a serious shot across Tesla's bow and will probably have a negative effect on company valuation and stock price. Essentially, it's FUD that rings true, even among Tesla loyalists.He doesn't half waffle on. 5:20, more than half way through the video, before he gets to the point. And if he/she thinks this doesn't happen with other brands, they're just lucky not to have experienced that. I have and I'm far from an experienced driver. Definitely agree Tesla should be better than that, though. And I'm sure they will be, they're just in explosive growth phase and unchartered territory as I see it.

This is interesting:
The world’s largest roofing company just launched a new solar startup
Not like a Tesla solar roof, but if they get a product like that it will be a major competitor.
Not doneOne question I'm still unclear on: are Q4 reports ever decoupled from year-end reports? Could Tesla release Q4 earnings, then release year-end earnings thereafter? Or is that just not done?

True - so if you want to capture a permanent increase in the stock price, which I believe @KarenRei wants to, then keeping expiry farther out reduces theta decay.
Is there any rule of thumb when theta decay speeds up - around 30 days from expiry?
120 days outTrue - so if you want to capture a permanent increase in the stock price, which I believe @KarenRei wants to, then keeping expiry farther out reduces theta decay costs. (Which are still a constant cost.)
