What it means
The daily work is less glamorous than the title suggests. Most of it is building and maintaining spreadsheet models, reading filings and transcripts, and tracking the handful of operating drivers that actually move a company's earnings.
Sell-side analysts sit at brokerages and investment banks and publish research read by institutional clients, complete with ratings and target prices. Buy-side analysts work inside asset managers, hedge funds or pension funds, and their output stays private because it directly informs positions the firm is taking.
Coverage is usually organised by sector so that an analyst develops genuine depth, following perhaps ten to twenty companies in semiconductors, food retail or European banks. That specialisation is what lets them spot when a reported number does not match what the industry is telling them.
Valuation work typically blends two approaches: a discounted cash flow model built from forecast cash flows, and relative valuation using multiples such as price to earnings against comparable companies. Where the two disagree, explaining the gap is often the most valuable part of the note.
Career progression usually runs from associate through analyst to senior or lead analyst, often alongside a professional qualification such as the CFA charter. Many analysts later move to portfolio management, corporate strategy or investor relations, since the skills travel well.
In practice
Real-world examples.
Example
A sell-side analyst covering airlines publishes a note downgrading a carrier to hold after channel checks suggest forward bookings are softening. The stock falls 4% on the morning the note is released.
Example
A buy-side analyst at a pension fund spends three weeks on a packaged food company, concludes the market is underestimating the cost of a factory relocation, and recommends the fund avoid the stock despite an attractive headline multiple.
Example
A credit analyst at an insurance company reviews a proposed $50,000,000 bond purchase, models the issuer's interest cover under a recession scenario, and approves the investment only at a shorter maturity than originally offered.
Formula
Calculation
Earnings per share = net income / shares outstanding
Target price = forecast earnings per share x justified price to earnings multiple
Implied upside = (target price - current price) / current price
An analyst covering a mid-sized industrial company forecasts net income of $96,000,000 next year on 30,000,000 shares outstanding. Forecast earnings per share is $96,000,000 / 30,000,000 = $3.20.
Comparable listed peers trade on about 18 times forward earnings, and the analyst judges this company deserves the same multiple given similar margins and growth. The target price is $3.20 x 18 = $57.60.
With the shares currently at $46.00, the implied upside is ($57.60 - $46.00) / $46.00 = $11.60 / $46.00 = 25.2%, which supports a buy rating. The analyst would also flag the sensitivity: at a 15 times multiple the target falls to $48.00 and the case largely disappears, so the recommendation depends on the peer multiple holding.Case study
Seen in the real world.
The following is an illustrative and entirely fictional example. Marisha, an invented junior analyst at a fictional research house called Brenton Kell, was asked to initiate coverage on a mid-cap industrial group. Her model produced forecast earnings per share of $3.20 and, applying the 18 times multiple her peer group traded on, a target price of $57.60 against a market price of $46.00.
Her supervisor pushed back on the multiple rather than the earnings. Two of the five peers in her comparison set had recurring service revenue worth roughly half their profit, which justified their higher ratings, and stripping them out took the fair multiple closer to 15 times and the target to $48.00.
In this illustrative case the note was published with a hold rating and an explicit explanation of why the peer set had been narrowed. Nine months later the company traded at $49, and the fictional firm's clients remembered the analyst who had explained her multiple rather than the one who had simply averaged the sector.
Watch out
Common mistakes.
- Anchoring the target price on the current share price and reverse-engineering assumptions until the model agrees with it.
- Copying a peer group multiple without checking whether those peers have the same growth, margins and business mix.
- Confusing a good company with a good investment, since a well-run business can still be too expensive at the price on offer.
Questions
People also ask.
What qualifications does an investment analyst need?
Usually a degree in a numerate or business subject plus strong modelling skills, with the CFA charter the most widely recognised professional credential.
What is the difference between sell-side and buy-side analysts?
Sell-side analysts publish research for external clients and are measured partly on the value of that research, while buy-side analysts write for their own firm and are measured on the performance of the positions taken.
Are analyst ratings reliable?
They are useful as research rather than instructions, since ratings skew toward buy across the market and the reasoning in the note usually matters more than the label on the front page.
