My depth of stock trading stops at the buy low sell high level. Can someone explain a little more if you have time? What would have happened to those trades if splunk had went down 20%?
They bought $127 call options (the right to buy Splunk at $127) while Splunk was valued at $119 and the options were due to expire in one day. That's a cheap option to buy, given the improbability of a sudden jump like that. The only way the buyer could make a profit would be for Splunk to go higher than $127 and if it went significantly higher, they'd stand to make an eye-watering return-on-investment multiple in on…
Calls are the right to buy at $127 - the shares received can then be sold at market price.
Puts are the right to sell at $127 - the short position can then be closed by buying at market price.
