I do want to call in the fact, that if you don't leverage, you will lose equal or less nominal $ by holding this kind of assets vs stock, so your description of danger is correct when you're leveraged, but otherwise it's not.
1.Now, most ppl do this for leverage, but you don't have to.
For example(assume SP $300 for ease of calucation), If I buy 10 contracts of $150 strike TSLA, instead of 1000 shares($300K), I will pay around $150-$153K, deploy about 50-51.5% of the capital.
2. If stock dropped 50%, I would lose around 150K in shares, but probably around 120K in options, as options would recover some time value and be priced around $30 (price for Jan 19 if Tesla was 150 - sounds about right?)
Furthermore, if Tesla dropped to $100, I would have lost $200K in shares, and loss in options is limited to invested $150-$153K, but option would still probably be worth some $10, so loss would be around $140K
3. Taken to logical extreme, if TSLA goes to 0, I lose 150-$153K in options, but $300K in shares.
4.So DITM calls are actually safer, if you don't leverage yourself.
