Each month, a single set of numbers arrives and reminds markets how much uncertainty underlies even the most watched economies. This Friday, Wall Street awaits July's jobs report — nonfarm payrolls and unemployment figures — not with consensus, but with unusually wide disagreement about what those numbers will show. When analysts cannot agree on what to expect, the market has no anchor, and whatever reality delivers becomes a shock to someone's position. In that gap between expectation and outcome, volatility is born.
