Why two RV values? Yang-Zhang RV (33.2%, OHLC-based) captures intraday volatility, while ORATS RV (35.3%, close-to-close) uses only closing prices. For BIIB, YZ is lower — suggesting closing prices reflect more volatility than intraday action. VRP is computed using ORATS RV to match the IV source. Gap: 2.1pp. Full IV Analysis →
Earnings impact: Raw VRP (+4.8pp) includes an IV premium from upcoming earnings (20d). Excluding this premium, VRP is 0.0pp. The 5pp gap is earnings-driven — not a structural edge.

Biogen shows moderately favorable conditions for premium selling. Yang-Zhang realized volatility reads 33.2% over 20 days versus a 31.9% 60-day baseline. The RV Ratio (HV 20d / IV 30d) is 0.88, indicating calming conditions relative to implied expectations. A health care sector component tracked by volradar. For premium sellers tracking BIIB, this ratio suggests options are likely priced for more movement than the stock is currently delivering.
Looking at the past 18 trading days, BIIB's RV ratio has been trending lower. The ratio ranged from 1.11 to 0.88, with the current reading of 0.88 near the lower end. 15 of 18 days showed seller-favorable conditions. A gradual decline is often more sustainable than a sharp drop, suggesting BIIB may remain in this lower-vol regime for a while.
Based on current realized volatility, traders can expect BIIB to move approximately ±$3.71 (2.1%) per day and ±$8.29 (4.7%) over five trading days. At a stock price of $177.09, these ranges are derived from the Yang-Zhang volatility model which accounts for overnight gaps and intraday range — more accurate than simple close-to-close calculations. Premium sellers typically place short strikes outside these 1-standard-deviation ranges to achieve approximately 68%+ probability of profit.
Current conditions on BIIB point toward range-bound strategies like iron condor. Moderately calm conditions (ratio 0.88). Range-bound behavior favors iron condors. Iron Condor benefits from time decay while defining maximum risk on both sides — a structure that suits BIIB's current volatility profile where directional edge is limited but overall conditions are acceptable for premium collection.
BIIB has earnings in roughly 20 trading days. While not immediate, this proximity means implied volatility may begin expanding as the market prices in event risk. Premium sellers should factor this into DTE selection — positions expiring before earnings avoid the binary risk entirely, while positions spanning the event carry significantly higher uncertainty.
VolRadar tracks BIIB daily as part of the S&P 500 universe, providing Yang-Zhang (OHLC-based) realized volatility across 10, 20, and 60-day windows, RV ratio analysis, expected move calculations, and premium selling condition assessments. Note: RV values on this page use the Yang-Zhang estimator (captures overnight gaps); VRP and RV Ratio use ORATS close-to-close RV to match the IV data source. Data is updated daily after market close (~6:00 PM ET). All analysis is for educational purposes only and does not constitute financial advice. Options trading involves significant risk of loss.

Biogen currently shows a weak premium selling signal. Consider waiting for conditions to improve. The VRP Analysis page tracks historical premium edge trends that may signal when conditions are turning.
Biogen's IV Rank is 34%, indicating relatively cheap options. While premiums are thinner, low IV can present opportunities for option buyers or for sellers who focus on probability rather than absolute premium. See the IV Analysis page for detailed breakdown.
VolRadar tracks Biogen across 10 analysis dimensions updated daily after market close. The premium selling signal combines VRP edge, volatility regime, IV Rank, earnings proximity, and market-wide conditions into a single actionable verdict. Each sub-page goes deeper: VRP Analysis for the implied-vs-realized spread, IV Analysis for peer comparisons, Expected Move for strike placement, Earnings Crush for event history, and the Strategy Builder for modeling specific trades.
Biogen currently shows a weak premium selling signal because multiple factors are unfavorable. Consider waiting for conditions to improve.
Biogen's volatility is measured using two key metrics. The RV Ratio compares realized volatility (ORATS HV 20d) to implied volatility (IV 30d). When the RV Ratio drops below 0.85, realized movement is well below what options are pricing — the sweet spot for premium sellers. VRP (Volatility Risk Premium) measures the gap between IV and HV in percentage points — positive VRP means options are overpriced relative to actual movement. Current RV Ratio: 0.88.
Biogen's snapshot: IV Rank 34% (average premiums), VRP +4.8pp (options overpriced), RV Ratio 0.88 (normal volatility). These three metrics work together — IV Rank shows historical context, VRP shows current overpricing, and RV Ratio shows the volatility trend. See the IV Analysis page for peer comparisons and deeper breakdown.
VolRadar provides 10 analysis pages for Biogen: Overview (this page), Premium Selling (signal and strategy verdict), VRP Analysis (volatility risk premium history), Expected Move (range and probabilities), IV Analysis (implied volatility breakdown and peer comparison), Earnings Crush (historical post-earnings IV patterns), Options Strategy Builder (18 presets + custom calculator), Covered Call Analysis (ranked by CC Score), Wheel Strategy (CSP calculator and viability), and Support & Resistance Walls (options-derived price levels).
Key risks for Biogen right now: earnings in 20 days — the largest source of overnight gap risk that can blow through short strikes. These risks are worse when combined — for example, selling into earnings with negative VRP removes both your statistical edge and your safety margin. Use VolRadar's sub-pages to contextualize: VRP Analysis for edge confirmation, IV Analysis for premium adequacy, and Expected Move for strike distance guidance.
Based on Yang-Zhang realized volatility, Biogen has a 1-day expected move of ±$3.71 (±2.1%) and a 5-day expected move of ±$8.29 (±4.7%). This means the stock is expected to trade between $169 and $185 over the next week with approximately 68% probability.
