One move, two parts. Recheck every number by hand.

A LONG meme’s dollar price is two prices multiplied

Each LONG meme trades against a Robinhood stock token, so its pool gives its price in the stock. Multiply by the stock’s own dollar price and you get the meme’s dollar price.

So the dollar price can move because the meme moved against the stock (R), because the stock moved (S), or both.

Splitting the move into a stock part and a meme part

Over any window, the stock moves by s and the meme’s price in the stock moves by m. The dollar move is then:

We give each side its own move plus half of the shared bit, the Shapley split. It is the average of “stock first, then meme” and “meme first, then stock”, so neither side gets favoured by the order.

Stock’s share of the move is the stock part divided by the total. When the two parts point in opposite directions it can go above 100% or below 0%.

The interaction, shared half and half

The term s·m exists only because both prices moved at once: a meme that rose 50% in a stock that rose 10% gains an extra 5 points on top of 60. It belongs to neither side alone, so it is split evenly, like a weight placed across both pans of a balance.

Which tokens count, and which pool we read

A token is treated as a LONG launch when one of these recognises it:

For each token we read its largest pool quoted in a stock token. If another pool, say one quoted in USD, holds more liquidity, the token carries a “Bigger pool elsewhere” flag. Tokens whose main pool holds under $5,000 are marked thin and hidden unless you ask to see them.

Tokens we leave out

Some LONG tokens have no pool we can split: they are quoted only in a leveraged token, in USDG or in another meme. They keep a page, but stay out of the overview.
