About DXCM
Dexcom (DXCM) is a major company in continuous glucose monitors. Options traders on DXCM tend to watch device demand, competition and earnings, since these can drive large moves in the share price.
DXCM for options traders
Dexcom is a pure-play continuous glucose monitor (CGM) maker, and that narrow focus is exactly what keeps its implied volatility (IV) structurally elevated. The stock is acutely sensitive to earnings surprises — guidance changes around patient adoption, reimbursement coverage, and international expansion routinely produce large single-session moves. Competitive pressure from rival CGM platforms and any shift in Medicare or insurance policy can reprice the stock abruptly, making IV spike well outside of earnings windows too.
Options liquidity is solid for a mid-cap medical-device name, with enough open interest across near-dated strikes to support multi-leg structures. Long straddles and strangles are popular into earnings given the history of outsized moves in either direction. Between catalysts, when IV retreats, premium sellers often deploy iron condors or short strangles to harvest elevated time value within an expected trading range. Defined-risk spreads — vertical calls or puts — suit traders with a directional lean who want to manage the cost of exposure on a name that can gap sharply.

Historical backtest: how a Iron Condor on DXCM would have performed
We approximated a Iron Condor on DXCM, entered repeatedly over the past year (92 historical entries, each held to expiration) with Black-Scholes-modelled entry premiums. Here is how that would have played out on real DXCM price history — an educational backtest, not a prediction of future returns.
Approximate: entry premiums are modelled with Black-Scholes from trailing realised volatility, held to expiration and settled against the real historical close. Real fills, implied volatility and slippage differ — treat it as directional context, not exact returns.
Implied volatility
DXCM is currently trading with elevated implied volatility, so its options carry richer premiums. On the options we scanned that was around 37% implied volatility, and higher implied volatility means richer premiums and wider expected moves.
Options on DXCM currently price in about 37% implied volatility, versus roughly 46% the stock has actually realised over the past month. The two are roughly in line, so neither buying nor selling premium has a clear volatility edge here.
DXCM's IV Rank is 16/100: implied volatility sits 16% of the way between its 20-day low (33%) and high (57%), and is above 24% of recorded days. Premium is historically cheap, which favours net-debit strategies like long options and debit spreads.
Off that volatility, the options market is pricing a move of about ±$9.77 (±11%) in DXCM by 2026-10-02 — a range of roughly $80.47 to $100. Strikes inside that band hold most of the premium and see most of the action.
Across strikes, puts and calls on DXCM carry a fairly symmetric implied volatility — no strong directional fear is priced in either way.
DXCM options chain highlights: open interest, volume and skew
The live DXCM options chain shows a put/call open-interest ratio of 0.34 (bullish-leaning (more calls)), with at-the-money implied volatility near 35.9%. Open interest clusters at the $95 call — a common resistance "wall" — and the $85 put, a support "wall": the strikes option writers are most exposed to into expiration.

DXCM insider trading activity (SEC Form 4)
Open-market insider transactions at DXCM over roughly the last six months, from SEC Form 4 filings. Open-market buys are the rarer, more telling signal — routine selling under pre-arranged plans is common, so read a net-selling figure with that in mind.

Liquidity and tradeability
DXCM options are thinly traded, with wide bid-ask spreads around 22.6% near the money that eat into any edge — favour simple single-leg or tight defined-risk trades, and always use limit orders.
Earnings & IV crush
DXCM's next earnings report is due around October 29, 2026. Options that expire after it price in a binary move, so their implied volatility is elevated and usually collapses right after the announcement — an "IV crush". If your expiration falls before this date, the trade sidesteps the event.
