How SI BONE INC looks technically

SI BONE INC (SIBN) is trading 22.7% above its 200-day average, the long-term trend line — a longer-term uptrend. Its 50-day average crossed above its 200-day average about 18 trading days ago — a "golden cross", a bullish long-term signal. A strong uptrend is in place — ADX, a 0–100 trend-strength gauge, is 33, with buyers in control. Momentum is neutral — its 14-day RSI (a 0–100 momentum gauge) is 68, neither overbought (above 70) nor oversold (below 30). It just made a new 20-day high, its first since 2026-01-09, pushing above its recent trading range. Trading volume is running unusually high — about 2.7× its 30-day average, a sign of heightened interest.

Position in its 14-day rangeit is trading right at the top of its 14-day range ($17.65 to $20.05) — its "stochastic" reading is 96 out of 100, where 0 would mean closing exactly at the 14-session low and 100 exactly at the high. This measures WHERE the price sits inside its recent range, which is a different question from the RSI beside it: RSI is a momentum gauge, measuring how FAST the price has been moving, so a stock can drift quietly to the bottom of its range with an ordinary RSI, or fall sharply and still sit in the middle.

A level is a price this company reversed or paused at more than once — they describe past behaviour, not a forecast of where the price will go.

Wave structure

Its recent swings can be read as a five-part upward sequence — what Elliott-wave chartists call an impulse — now in leg 4 of five, a pullback against that direction.

This labelling fails — stops being a possible reading at all — if it closes below $18.16.

It is the only labelling that fits these swings, though its proportions are not the textbook ones.

On past moves of this shape the leg has usually ended somewhere between $18.16 and $18.62 — that is where it has tended to end if the count holds, not a forecast of where the price goes.

This reading has stood for 2 trading days, since 2026-08-20.

  • Consensus EPS estimate-$0.1281 next reporting period, as of 2026-08-24

Change over time is not available yet: it needs two readings of the same reporting period at least 30 days apart, and we have been recording these estimates since 2026-08-04. An estimate for a DIFFERENT quarter is not a revision, so a reading from before the last report is never compared with one after it.

The consensus estimate for the next reporting period, and how it has moved between readings of that SAME period. A change is measured only between readings estimating one period — when a company reports, the consensus moves to the next quarter and the two numbers are not comparable.
