Which option correctly identifies the fundamental effect of liquidity on prices?

• A. Liquidity acts as a magnet for price
• B. Larger depth dampens price impact from trades
• C. Liquidity eliminates all price volatility
• D. Liquidity guarantees price equality across venues

Answer: (A)

Liquidity shapes how prices behave by giving market participants ready counterparties to trade with at nearby levels. When there is plenty of buying and selling interest around a price, trades can be absorbed with only small moves, so the price tends to stay close to that liquid level. In this sense, liquidity acts like a magnet for price—prices gravitate toward the levels where there is abundant liquidity because those levels offer easier execution and less friction. This anchoring helps prices incorporate new information smoothly and reduces the risk that a trade will push the price far away from fair value.

While deeper liquidity (more orders nearby) does dampen how much a trade moves the price, and is an important mechanism, the fundamental takeaway is that liquidity pulls prices toward liquid levels. The other statements—liquidity eliminating all volatility or guaranteeing price equality across venues—are inaccurate, as even liquid markets experience price movement and cross-venue differences can occur.
