Considering the Pilbara Minerals Ltd (ASX: PLS) share price has gained a whopping 546% over the last 12 months, it's easy to assume its best day ever would have occurred recently. But it didn't.
In fact, Pilbara's best day ever on the ASX was way back in 2015.
Now, for clarity and simplicity's sake, we won't be looking into any gains the Pilbara Minerals share price experienced when it was trading for under 10 cents.
As long-term market watchers will know, there are a number of days on Pilbara's chart when it started the session trading for 1 cent, and gained another cent, therefore soaring 100%. Those instances won't be covered here.
Now we've got that housekeeping out of the way, let's take a look at the lithium and tantalum producer's best day on the ASX.
The Pilbara Minerals share price's best day ever
The best day ever for the Pilbara Minerals share price was June 17, 2015. That day, Pilbara's shares started out trading for 10 cents, before rocketing to close at 14 cents. That's a massive gain of 40% in a single session.
Perhaps what's most interesting about the Pilbara share price's sudden ascension that day, is the fact it was spurred by nothing. The company hadn't released a single piece of price-sensitive news for nearly 10 days.
However, the prior week, the company had updated the market on a research report into Pilbara Minerals.
As time has gone on, that research report has been removed from Pilbara's website. Though, perhaps its contents helped spur the Pilbara Minerals share price's best day ever.
The company's best day on the ASX in recent years was on 17 September 2020. That was the day of Pilbara's annual general meeting, and it saw its share price gain 17.4%.
