Lesson 10 of 12

When companies plan to grow, they hire; when they expect trouble, they freeze hiring or cut jobs. Job postings data captures these decisions in near real time by tracking millions of listings on company websites and job boards. Investors use it to spot companies expanding into new products or regions, detect slowdowns before they appear in results and track the overall labour market ahead of official reports. Employee review and headcount data add further clues about company health.

Types of labour data#

DataWhat it showsExample sources
Job postingsNumber, type and location of open rolesCompany career pages, job boards, aggregators
Job descriptionsSkills and technologies soughtText analysis of listings
Headcount estimatesEmployee counts over timeProfessional networking profiles
Employee reviewsMorale, management ratings, outlookReview sites
Layoff trackersAnnounced job cutsWARN notices, news, layoff databases
Official statisticsJOLTS openings, payrolls, claimsGovernment agencies. See Employment Data and Non-Farm Payrolls

Company level signals#

  • Rising postings in specific areas: a company hiring many AI engineers, salespeople in a new country or factory staff may be preparing a launch or expansion.
  • Hiring freezes: a sharp drop in postings can signal weaker demand or cost cutting before results show it.
  • Mix of roles: a shift from engineering to sales may signal a product reaching commercialisation.
  • Employee sentiment: falling review scores and rising departures can precede operational problems.

Macro uses#

IndicatorSignal
Total postings on major job sitesLabour demand, often ahead of official job openings data
Postings by sectorWhich industries are expanding or contracting
Wage data in postingsWage pressure, linked to inflation. See Inflation
Layoff announcementsEarly warning for jobless claims and unemployment. See Recession Indicators

Job board operators such as Indeed have published postings indices that economists use alongside the official JOLTS report, which is released with a lag of more than a month.

Limits and pitfalls#

IssueExplanation
Postings are not hiresSome listings stay open for months or are never filled
"Ghost" or evergreen postingsRoles posted to collect resumes rather than fill specific jobs
DuplicatesThe same job on many sites
CoverageSmaller firms and some industries post less online
Changes in recruiting practiceShifts to referrals or recruiters reduce public postings
Mapping to companiesSubsidiaries and brands must be linked to the right ticker

Using labour data in research#

  1. Track changes, not levels, compared with a company's own history.
  2. Compare with peers in the same industry.
  3. Combine with other data, such as web traffic and card spending. See Web Traffic, App Downloads and Search Trends.
  4. Test predictive value for revenue or returns before relying on it. See Signal Discovery.

Frequently asked questions#

How do investors use job postings data?#

To detect company expansion or slowdown, new product plans and labour market trends before they appear in official reports or results.

Are job postings a good indicator of the economy?#

They are a timely gauge of labour demand, but postings do not always equal hires, so they work best combined with other data.

What are the limits of job postings data?#

Postings may remain open without hiring, duplicates and ghost listings inflate counts, and coverage varies by industry and company size.
