@Nifty Singh bhai, I am always skeptical about "futuristic businesses" and in general high PE stocks. As sometime or the other, earnings will have to justify the valuation. When that "margin call" comes is anybody's guess.
If I remember correctly, the mgmt said that their current capacity is around 4 drones a day, in one of the interviews (I could be wrong here, or this info could be dated). Now, whatever little knowledge I have of this field, I don't think this number justifies the lofty valuations, unless there are some concrete plans to scale up.
While I did apply in ideaforge IPO, I was clear to sell 75-80% on listing. Didn't get allotment, and listing was on expected lines superb, so totally ignored thereon.
