Risk Management

Research across 200+ tradeable items reveals a mean pairwise correlation of just +0.019. In practical terms, OSRS items move independently of each other. A crash in one item's price tells you almost nothing about what another item will do.

This is a gift for risk management. In real-world financial markets, assets often crash together during panics (correlations spike to +0.8 or higher). In OSRS, diversification works exactly as textbooks describe: spreading across multiple items genuinely reduces risk because losses on one item are unlikely to coincide with losses on others.

A counterintuitive finding: having more capital barely increases GP/hr. Research shows that a player with 5M GP can generate roughly 2.7M GP/hr, while a player with 200M GP generates about 3.4M GP/hr. That is only a 26% increase for 40x the capital.

The bottleneck is buy limits, not capital. Once you can afford to fill a buy limit, additional capital sitting in your inventory does nothing. The optimal approach is to fill all 8 GE slots with different items rather than concentrating on a single expensive one.

This also means new players are not at a significant disadvantage. You can achieve nearly maximum efficiency with a modest cash stack spread across several items.

Many players assume that when an item drops below its High Alchemy value, it is a “free money” buy — just buy and alch for guaranteed profit. Research shows this strategy has only a 48% win rate, which is worse than a coin flip.

The problem is selection bias. Items trading below their alch floor are there for a reason: they are typically illiquid, low-demand items that few players want. The alch floor creates a theoretical price floor, but if you cannot sell the item on the GE (because nobody wants it) and must alch it yourself, you are spending time and nature runes that eat into the margin.

Use the alch floor as a reference point, not a trading signal. It is visible on item charts for context, but do not build a strategy around it.

The May 2025 increase to 2% GE tax had a measurable impact on the flipping landscape. At least 28 mid-tier items became unprofitable overnight — items that previously had thin but positive margins after 1% tax now have negative margins at 2%.

The 100–10,000 GP price tier was hit hardest. Items in this range often had margins of 1.5–3%, which was viable at 1% tax but not at 2%. The tax effectively eliminated the lowest tier of flipping.

Penny items (under 100 GP) are largely immune because the 2% tax rounds down to 0 or 1 GP. High-value items (250M+) hit the 5M GP cap, making them proportionally less affected. The sweet spot for tax efficiency is either very cheap items or very expensive ones.

The simplest effective approach: divide your capital by 4 and allocate one quarter to each active GE slot. With 8 slots available, this means having 4 active flips at any time with capital in reserve for opportunities.

Why not use all 8 slots? In practice, managing 8 simultaneous flips requires constant attention. Having 4 active slots with capital ready lets you respond quickly to new signals without needing to cancel existing offers.

Never concentrate more than 25% of your total capital in a single item. Even high-confidence signals can fail — a game update, bot ban wave, or unexpected event can move prices against you. With items being uncorrelated (mean correlation +0.019), diversification is your strongest risk reduction tool.
